RFID technology has many promising applications. Overall, respondents were positive about RFID's potential. Most saw opportunities in inventory control, logistics/supply chain management and library management. Some concerns remain around cost and standardization, but further development is expected in medical uses and other industries. With refinements, RFID may provide significant benefits for tracking, access control and customer services.

3. RFID

 RFID = Radio Frequency Identification
 Electronic labeling and wireless identification of
objects using radio frequency
 Tag carries with its information
 a serial number
 Model number
 Color or any other imaginable data
 When these tags pass through a field generated by a
compatible reader, they transmit this information
back to the reader, thereby identifying the object

4. RFID components

 A basic RFID system consists of these components:
 A programmable RFID tag/inlay for storing item data;
 Consisting of an RFID chip for data storage
 an antenna to facilitate communication with the RFID
chip
 A reader/antenna system to interrogate the RFID
inlay
 Application software and a host computer system

5. RFID Tag

 The RFID tag consists of an integrated circuit (IC)
embedded in a thin film medium.
 Information stored in the memory of the RFID chip is
transmitted by the antenna circuit embedded in the
RFID inlay via radio frequencies, to an RFID reader
 3 types
 Passive
 Semi-passive
 Active

6. Types of RFID Tags

Active Tags Semi-passive Tags Passive Tags
• Use a battery • Contain built-in • Derive their power
• communicate over batteries to power the from the field
distances of several chip’s circuitry, resist generated by the
meters interference and reader
circumvent a lack of • without having an
power from the active transmitter to
reader signal due to transfer the
long distance. information stored
• They are different
from active tags in
that they only transmit
data at the time a
response is received
